標(biāo)準(zhǔn)材料:密封環(huán):填充改性的熱塑性材料,膨脹環(huán):丁腈橡膠NBR
應(yīng)用范圍:OB型活塞密封件主要用于重型液壓設(shè)備,特別適合于雙作用活塞,這類密封件適用的工作壓力高達(dá)50MPa,在某些情況下還可更高 設(shè)計(jì)選用時(shí)請(qǐng)參考Parker公司OK系列標(biāo)準(zhǔn)。
特點(diǎn),形狀小,耐沖擊負(fù)荷,即使保壓很長(zhǎng)時(shí)間后，起動(dòng)和運(yùn)動(dòng)的摩擦都很低,由于液壓缸密封圈為開(kāi)口式結(jié)構(gòu)，故無(wú)需要輔助工具便容易安裝在整體式活塞上,耐磨性高,由于液壓缸密封圈特殊的材料性能，在高壓和大間隙下均有較強(qiáng)的抗擠壓能力,適用于按ISO 7425-1國(guó)際標(biāo)準(zhǔn)的溝槽
